J-IG FOR CONCENTRATING ORES.

Specification of Letters Patent.

Application filed January 31, 1920. Serial No. 355,496.

To all whom it may concern: I

Be it known that I, JOHN R. CoMBs, a

' citizen of the United States, residing at Tipton Ford, Missouri, in the county of Newton and State of Missouri, have invented certain new and useful Improvements in J igs for Concentrating Ores, of which the followin is a specification.

his invention relates to improvements in jigs for concentrating ores.

An important object of the'invention is to provide an improvement ofthat type of jig in which the agitation of the water or other fluid used in concentrating the ores is obtained by means of a plunger acting against the body of the fluid. Theseplungers are made of solid construction and it is therefore impossible to vary the impact with which they engage the same. I have provideda jig wherein the plunger is provided with.

openings covered by valves which may be opened and closed while the'plunger is in operation to regulate the amount of surface of the plunger which impacts the water. In the concentration of ores the ore passing through the jig will change any character as often as two and three times a day and it will be obvious that in the concentrating of heavy ores a greater agitation of the water is necessary than in the concentration of light ores. If too great an agitation is applied to the water which is passed through the light ores it is altogether possible that the mineral born by the ores will be carried away with the water and not merely separated from the ores sufficiently to allow it to settle to the bottom of the jig.

Other objects and advantages will be apparent throughout the course of the following description.

In the accompanying drawings, Figure 1- is a sectional view taken through a'jig embodying my invention, the section being taken on a line indicated as 1-1. onFigure 3.

Fig. 2 is a perspective of the plunger used in my jig.

Figure 3 is a plan v1ew of the jig, and

Figure 1 is a perspective of the guides and the opening protection sheath.

Referring now more particularly to the drawings the numeral 10 indicates a suitable receptacle having arranged thereon the side a guide frame 11 within which reciprocates a plunger 12.

Within the receptacle 10 adjacent the top thereof and extending over the space not occupied by the guiding frame 11 is arranged a supportlng strip of foraminous material. v13upon which theores 14, which are being concentrated, repose. a v The plunger 12 is secured to a connecting rod 15 which is provided upon its upper end with an eccentric strap 16. This eccentric strap 16 surrounds an eccentric 17 secured to or'formed-upon a shaft 18 which is rotated in any suitable manner. Formed in the plunger 12 are openings 19 the sides of which are protected by metal tube 20. I

Arranged upon the upper surface of the plunger at each of the openings 19 and hav- Patented May 9, 1922.

mg one end open are guides 21 in which are slldably mounted slide valves 22. Intermediate the openings 19 as at 23 a shaft 24. is rotatably mounted in the plunger 12. This shaft is provided adjacent the upper surface of the upper end of the shaft extends through a guide 26 secured to the eccentric strap 16 and is provided with an operating wheel 27. The inner end of the slidevalves 22 are reduced as at 28 and have formed upon one side thereof a rack 29 engaging the gear 25 of the shaft 24. 1

It will be obvious that by rotating the wheel 27 the position of the valves 22 may be altered'during the operation of the plunger and the surface of the plunger which engages the water may be thereby altered. As many changes are possible in the shape, size and arrangement of the various parts herein shown, and described, I do not limit myself to the specific structure herein set forth, but may make any such changes without departing from the spirit of the inven tion, or the scope of the subjoined claims.

What I claim is:

plunger 12 with a gear 25 and the 1 In a jig for concentrating ores embodying a suitable receptacle having therein stationary means for supporting the ores being concentrated, a plunger for agitating the fluid by which the ores are concentrated, means fo varying the size of the fluid engaging surface of said plunger.

2. In a jig for concentrating ores embodyinga suitable receptacle having therein stationary means for supporting the ores being concentratedQa plunger for agitating the fluid by which the ores are concentrated, means for varying the size of the fluid engaging surtaceof said plunger, during the operation of said plunger.

3. In a jig for concentrating ores embodying a suitable receptacle having therein stationary means for supporting the ores being concentrated, a plunger for agitating the fluid by which the ores are concentrated, means for adjustably varying the amount of agitation imparted to the fluid by said plunger during the operation of said plunger, comprising valves adjustably closing openings formed in said plunger.

4. In a for concentrating ores, a re ceptacle, stationary ore supporting means arranged therein, a plunger'for agitating the fluid by which the ores are concentrated, said plunger being provided with a plurality of openings, and valves arranged over said openings whereby the amount of agitation imparted to the fluid may be regulated.

5. In a jig for concentrating ores, a liquid receptacle, stationary means mounted in one end of said receptacle for supporting the ores being concentrated, a plunger mounted in the opposite end of said receptacle and provided with an opening, a slide valve mounted adjacent said opening and means for reciprocating said slide valve.

6. In a jig for concentrating ores, a liquid receptacle, means disposed in one end of said receptacle for supporting the ores being concentrated, a plunger disposed in the opposite end 01": said receptacle and provided with a pair of openings, slide valves mounted adjacent said openings, rack bars carried by said slide valves, and a pinion meshing with said rack bars.

In testimony whereof I aiiix my signature in presence of two witnesses.
